eslint-plugin-tsc

library2.0.0jsnpmunverified

ESLint plugin that wraps TypeScript compiler checks as an ESLint rule. Version 2.0.0 (September 2020) requires TypeScript 4+. It provides a single rule `tsc/config` that runs the TypeScript compiler on files linted by ESLint, reporting type errors and diagnostics. Unlike @typescript-eslint, which implements type-aware lint rules individually, this plugin directly invokes the full compiler, catching all type errors and compiler options like noUnusedLocals. Suitable for projects wanting to enforce compiler checks within ESLint without duplicating compiler options. Release cadence: infrequent, last release 2020.

Code

Verified usage

Verified import paths — ran on the pinned version, not inferred.

plugin

✓ module.exports = { plugins: ['tsc'] };

Add 'tsc' to plugins array in ESLint config, then use rule 'tsc/config'.

tsc/config

✓ "tsc/config": ["warn", { "configFile": "./tsconfig.json" }]

✗ "tsc/config": true

Rule requires options object with configFile path; severity can be 1 or 'warn'.

configFile

✓ "tsc/config": [1, { "configFile": "/absolute/path/tsconfig.json" }]

Absolute path recommended to avoid resolution issues.

Configures eslint-plugin-tsc to run TypeScript compiler checks via the tsc/config rule, overriding compiler options.

// .eslintrc.js module.exports = { plugins: ['tsc'], rules: { 'tsc/config': [ 'warn', { configFile: './tsconfig.json', compilerOptions: { noUnusedLocals: true, strictNullChecks: true } } ] } }; // Run ESLint on a TypeScript file // eslint src/index.ts

Debug

Known issues

breakingVersion 2.0.0 requires TypeScript 4+. Downgrade to 1.x for TypeScript 3.x compatibility.

fix

Use eslint-plugin-tsc@1.2.0 if using TypeScript <4.

affects: >=2.0.0

gotchaThe configFile path is relative to the current working directory, not the ESLint config file. Use absolute paths to avoid confusion.

fix

Specify an absolute path for configFile, e.g., path.resolve(__dirname, 'tsconfig.json').

affects: >=1.0.0

gotchaPlugin only provides a single rule 'tsc/config'. It does not include individual rules like '@typescript-eslint/no-unused-vars'.

fix

Use alongside @typescript-eslint for fine-grained lint rules if needed.

affects: >=1.0.0

deprecatedPlugin is thinly maintained; last release 2020. Consider switching to @typescript-eslint which is more actively maintained and integrates type checking.

fix

Migrate to @typescript-eslint/parser and @typescript-eslint/eslint-plugin.

affects: >=1.0.0

Errors

Common errors & fixes

Error: Could not find tsconfig.json. Please specify configFile in rule options.

configFile path is missing or incorrect.

fix

Add configFile to rule options with correct path, e.g., "configFile": "path/to/tsconfig.json".

Parsing error: The keyword 'import' is reserved

ESLint is parsing TypeScript as JavaScript. Need to configure TypeScript parser.

fix

Add @typescript-eslint/parser to your ESLint config: 'parser': '@typescript-eslint/parser'.

Definition for rule 'tsc/config' was not found.

eslint-plugin-tsc is not installed or not added to plugins array.

fix

Run npm install eslint-plugin-tsc --save-dev and add 'tsc' to plugins array.
